A taste of social media: #Royals. Major League Baseball closed out the 2015 season in grand style, as the Kansas City Royals rallied to win the World Series on Sunday with a five-run 12th inning that crushed the New York Mets’ hopes to extend the series. And if you think Royals fans in Missouri had plenty to cheer about on social media, Royals lovers in the San Antonio area had something to tweet about, too.

I woke up and checked: it wasn't a dream. #Royals #TookTheCrown. — Alan Bush, @alanbush

My San Antonio peeps should have enjoyed the #Royals play this postseason. KC is essentially the Spurs of MLB. Total team wins. — Jordan Korphage, @jordan_korphage

@markseibel I think #Royals are good as long as @GregAbbott_TX doesn't Tweet any congratulations — Gigi, @gigilehman, in response to Mark Seibel tweeting during the decisive game there were still three outs to play.

Hillary Clinton’s emoji query. Consider it a lighter moment in the controversy over presidential hopeful Hillary Clinton’s use of a private email server. USA Today reported the State Department recently released a batch of Clinton emails that included a downright happy-faced missive — an April 3, 2012, email to aide Philippe Reines asking how to get “smiley faces” on her new BlackBerry.

Reines responded he didn’t think so for email, noting Clinton would need to “type them out manually like :) for happy, or :-|| if you want to express anger at my tardiness.”

Well, isn’t that just ~_~.

Amazon kills its credit card reader. And then Square exhaled. Amazon has discontinued its Register mobile credit card reader just a little more than a year after its launch.

As The Verge reported, Amazon stopped selling the $10 card reader just before Halloween, and issued a statement on the service’s site that businesses will no longer be able to process Register purchases on Feb. 1, 2016. The Verge noted Amazon tried to ring up Register business with a tiny 2.5 percent per swipe processing fee, just below the 2.75 percent for the popular Square card reader. Amazon even offered a promotion rate as low as 1.75 percent per swipe.

Call it a loss leader that never led the way to big business. Amazon likely decided it didn’t get the massive user base needed to sustain the business, The Verge said.

Oculus founder sees cables as main obstacle to virtual reality industry. Take it from Palmer Luckey, original founder of the virtual reality company Oculus. If anything will trip up VR penetration into the mainstream, it’s going to be cables.

“Cables are going to be a major obstacle in the VR industry for a long time,” Luckey tweeted. “Mobile VR will be successful long before PC VR goes wireless.”

As TechCrunch noted, it’s why mobile VR headsets such as Google Cardboard have such mainstream popularity, relatively speaking. Mobile VR headsets have no strings, er, wires to tie them down. And while PC virtual reality packs more power than mobile, comfort has a might all its own, which TechCrunch said is key to get people past the “oh this is cool” five-minute demos that they forget about a half hour later.
